1 Claim. (01. 299-114) My invention relates to improvements in radially inwardly beyond these ports. The arnozzles adapted for spraying more or less heavy rangement is such that the heavy liquid disliquids, such as asphalt, macadam, tar, 110 penecharging through the ports will strike the intertrating oil, or the like. mediate portion of the wall of the recess 16 at An important object of the invention is to an angle, and rotary motion is imparted to the provide a nozzle which will produce the adoil so that it travels around this wall, and is vantages of the nozzle shown in Letters Patent conducted thereby inwardly so that it discharges, No. 1,816,645, granted to me under date of July while whirling, through the contracted opening 28, 1931, but which is simpler and is formed of 15. The spreader element is provided with a 10 fewer parts. forwardly flaring recess or opening 17, which is Other objects and advantages of the invention generally conical and leads at its contracted end, will be apparent during the course of the folinto the contracted opening 15.

It is to be understood that the form of ing an annular set of longitudinal, ports which 1 are circumferentially inclined and lead into the rear end of the long chamber, means whereby a hose may be attached to the rear end element for supplying the heavy liquid to the ports, and a spreader element bodily mounted upon the forward end of the tubular body portion and engaging at its periphery with the tubular body portion to close the tubular body portion at such point of engagement, the spreader element being provided centrally thereof with a contracted opening and being provided upon its rear end with a shallow forwardly converging conical recess and upon its forward end with a deep conical recess flaring forwardly, the inner reduced ends of both recesses leading into the contracted opening, the forward recess being considerably longer than the rear recess.
